Abstract

The efficiency of acetone extracts from guava, lime and pomegranate plants was studied against egg and adult female stages. Results showed that egg stage was more tolerant to all plant extracts than adult female. The biological aspects of T. urticae were affected by treating eggs and adult females with LC50 value of the three plant extracts. Incubation period of eggs, lifecycle and generation period prolonged, while female fecundity decreased. Lime was the most effective extract against eggs and adult females.
